OAP Core Clinical childhood budgets are annual — unused funds do not carry over to the next fiscal year. Invoices must be submitted before the Ontario fiscal year end (March 31). Foundational Family Services are delivered directly by providers and do not involve a family-managed budget, so there is nothing to "expire" on the foundational side.
Start with the short answer, then reveal deeper context where helpful.
The OAP operates on the Ontario government fiscal year: April 1 to March 31. Core clinical childhood budgets are allocated on an annual basis within this cycle. Any portion of the childhood budget not invoiced by March 31 is forfeited — unused funds do not roll into the following year.
To maximize your <a href="/oap-funding-guide" class="text-blue-600 hover:underline font-medium">OAP funding</a>, work with your provider to plan services from the beginning of the fiscal year. Delays in starting services — such as provider transitions or assessment periods — can reduce the effective budget available for that year. Building a therapy schedule early in the fiscal year avoids end-of-year rush and lost funds.

Families and their OAP-approved providers should track service delivery and invoice submission throughout the year to avoid losing unspent budget. Providers are responsible for submitting claims; families should confirm that invoices are being submitted regularly rather than in a single year-end batch.

Foundational services are delivered by regional service providers on a schedule set by MCCSS — families do not manage a Foundational budget and cannot "spend" or "lose" Foundational funding. These services continue regardless of fiscal year changes.
